Cable and wire harness

Abstract

A cable includes a plurality of electric wires, and a tape member spirally wound around an assembled article that is formed by twisting the plurality of electric wires. The thickness of the tape member is not less than 0.028 mm and not more than 0.090 mm, a width of the tape member is not less than 18 mm and not more than 35 mm, the tape member is spirally wound with an overlap of not less than ¼ and not more than ½ of the width thereof, and a tensile strength of the tape member is different between the longitudinal direction and the width direction and is smaller in the width direction than in the longitudinal direction.

What is claimed is: 
     
       1. A cable, comprising:
 a plurality of electric wires; 
 a tape member wound around an assembled article that is formed by twisting the plurality of electric wires; and 
 a sheath covering the tape member, 
 wherein a surface roughness of the tape member is different between a surface on an assembled article side and a surface on a sheath side and, the surface on the sheath side has a larger surface roughness than the surface on the assembled article side. 
 
     
     
       2. The cable according to  claim 1 , wherein the tape member is spirally wound around the assembled article,
 wherein the plurality of electric wires comprise a pair of first electric wires and one or two twisted-pair wires each formed by twisting a pair of second electric wires having a smaller outer diameter than the first electric wires and arranged between the pair of first electric wires in a circumferential direction, 
 wherein a twist direction of the twisted pair wire is different from a twist direction of the assembled article, and the twist direction of the assembled article is different from a winding direction of the tape member. 
 
     
     
       3. The cable according to  claim 1 , wherein the tape member is spirally wound around the assembled article,
 wherein the plurality of electric wires comprise a pair of first electric wires and one or two twisted-pair wires each formed by twisting a pair of second electric wires having a smaller outer diameter than the first electric wires and arranged between the pair of first electric wires in a circumferential direction, and the twist direction of the twisted-pair wire and the twist direction of the assembled article and the winding direction of the tape member are the same. 
 
     
     
       4. The cable according to  claim 1 , wherein the thickness of the tape member is not less than 0.028 mm and not more than 0.090 mm, and a width of the tape member is not less than 18 mm and not more than 35 mm. 
     
     
       5. The cable according to  claim 1 , wherein a tensile strength of the tape member is different between the longitudinal direction and the width direction and is smaller in the width direction than in the longitudinal direction. 
     
     
       6. The cable according to  claim 1 , wherein the tape member is spirally wound with an overlap of not less than ¼ and not more than ½ of the width thereof. 
     
     
       7. The cable according to  claim 1 , wherein the tape member is wound around the assembled article with an inclination angle of not less than 30° and not more than 60° with respect to the longitudinal direction of the cable. 
     
     
       8. The cable according to  claim 1 , further comprising an adhesive layer adhered to the surface of the tape member on the sheath side and thermally bonded to the sheath. 
     
     
       9. The cable according to  claim 1 , wherein the tape member is formed by laminating two or more layers of different materials in a thickness direction. 
     
     
       10. The cable according to  claim 1 , wherein the tape member comprises a nonwoven fabric of polyester, polypropylene, aramid fiber, nylon, acrylic fiber or glass fiber, and air permeability of the tape member is not less than 30 cc/cm 2 /sec and not more than 200 cc/cm 2 /sec. 
     
     
       11. The cable according to  claim 1 , wherein the tape member comprises paper. 
     
     
       12. The cable according to  claim 1 , wherein a resin constituting the sheath gets into microscopic recesses on the surface of the tape member on the sheath side. 
     
     
       13. The cable according to  claim 5 , wherein the tape member is configured so that the tensile strength in the width direction is not more than ⅔ of the tensile strength in the longitudinal direction. 
     
     
       14. The cable according to  claim 8 , wherein the adhesive layer is integrally provided on the tape member. 
     
     
       15. A wire harness, comprising:
 the cable according to  claim 1 ; and 
 a connector attached to at least one of end portions of the electric wires.
